Healdsburg's river gauge tells a different story from Guerneville's. Flood stage here is 23 feet, and the CNRFC describes how impacts build from farmland to town (CNRFC).
Healdsburg stages
| Stage | Height | What happens |
|---|---|---|
| Action | 20 ft | Monitor |
| Minor flood | 23 ft | Farmland and banks in rural areas along the river flood |
| Moderate flood | 27 ft | Some secondary roads south of town flood |
| Major flood | 29 ft | Homes, businesses and secondary roads in the lower sections of Healdsburg begin to flood; lower Alexander Valley floods |

Homes in the lowest parts of town near the river, and rural properties in the Alexander Valley and along the river south of town. Most of Healdsburg sits well above these levels.
